PETER BROTHERHOOD, OF LONDON, ENGLAND.

SPECIFICATION forming part of Letters Patent No. 630,773, dated August 8, 1899.

Application flied Aprn 24, '1899.

To @ZZ whom, t Wray concern:

Be it known that I, PETER BROTHERHOOD,

engineer, a citizen of England, residing atr 15v Belvedere road, Lambeth, London, England, have invented a certain new and useful Improvement in Centrifugal Governors, (for which I have applied for a patent in Great Britain, dated March 23, 1899, No. 6,354,) of which the following is a specification.

My invention relates to the construction of a centrifugal governor of a simple character which is very sensitive, as I shall describe with reference to the accompanying 'drawings.

Figures 1 and 2 vation.

The governor-spindle is made in two parts a and b. The one a is centered in a hole in the end of the engine or other shaft @which drives the governor by means of a crank-'pin CZ, attached to a. and engaged in a hole in the end of the shaft c. The other part h of the spindle is centered in a hole in the side of a lever e, which works the throttle or other regulating-valve. The meeting parts of a and b are inclosed in a rectangular hole ina heavy disk f and jointed to Jthe disk by pins g and h, passed through holes ofthe disk in such positions that when the ends of a and b1 are in their extreme position, the spindle being then in its shortest condition, the disk f lies at an angle to the axis of the spindle. When are sections, partly in ele-` the shaft and governor revolve, the disk f l Serial No. 714,310. (No model.)

tends to take a position at right angles to the axis of the spindle, and thus to lengthen the 'spindle moving the lever e, so as to more or less close the regulating-valve.

The holes for centering a and b and also that for the crank-pin of a are somewhat larger than the parts which enter them, so that there is freedom of movement for all the parts of the lever e.

Having thus described the nature of this ina yA centrifugal governor for engines, consisting of a spindle formed in two parts which are overlapped upon each other one of said parts being connected to a shaft of the en'- gine, a disk mounted on the overlapped por tions at an angle less than ninety degrees with the axis of the spindle, said disk having acentral opening in which the overlapped portions lie, a pivotal connection between l.vention and the best means I know of carry* 1 ing the same into practical eect, I claim-
